Abstract
A Fourier analysis of the signal generated by scanning the vertical wedges used in television and facsimile test patterns is presented. This reveals narrow concentrations of signal energy at certain points in the spectrum. When these concentrations of signal energy fall in regions of transmission distortion, such as the cutoff regions of transmission lines, the familiar ringing impairment results.
